Help with Sight Flow Indicators specifications:

Plain sight flow indicators are window-only devices. There are no moving parts to indicate flow. The unit may be mounted in any direction, but the flow is bi-directional. Plain sight flow indicators are used to detect easily-visible fluids, or the absence of such fluids. These devices are also used to detect color clarity and fluid turbulence.

Flappers are sight flow indicators with a flap that lifts when liquid flows. Devices may be mounted either horizontally or vertically, and have an upward flow. Typically, flappers are used with clear fluids.

Sight flow indicators have a rotor that turns when liquid is flowing. Devices may be mounted in any direction, but right-to-left flow is standard. Rotor-style sight flow indicators are designed for clear, translucent, or dark fluids.

Liquid drips into the indicator through a small opening in the end of the device. Units are designed for vertical applications, and only have downward flow. Drip tube sight flow indicators are recommended for applications with intermittent gravity or extremely low flow-rates.

Sight flow indicators have a flap that lifts when gas is flowing. Units may be mounted either horizontally or vertically, and have upward flow.

Butt welds are a fluid piping connection option for sight flow indicators. A butt weld implies a precision welding technique - for example, orbital welding - was used to make a liquid-tight weldment, minimizing risk of contamination to the process liquid. Applications using this type of connection include pharmaceutical, chemical, and dairy. A butt weld may help a component meet sterility or FDA requirements in a sanitary liquid system.

Bronze is a porous material that can be impregnated with oil, graphite or polytetrafluoroethylene (PTFE). Bronze is not suitable for heavily-loaded applications, but is useful where lubrication is inconvenient.

Dual windows are comprised of two glass discs held in position by a metallic housing, internal shims and gaskets. The double, tempered-glass window design provides added protection in applications where there is external mechanical impact or corrosion/erosion. FM Approval means that the indicator meets Factory Mutual (FM) system standards.
